METALLIC FIREPROOF WINDOW.

SPECIFICATION forming part of Letters Patent N 0. 788,878, dated. May 2,1905.

Application filed December 26, 1903. Serial No. 186,661.

vT0 all whom it may concern:

Be it known that I, Jonn BOGENBERGER, residing at Milwaukee, in thecounty of Milwaukee and State of Wisconsin, have invented a new anduseful Improvement in Metallic Fireproof Vindows, of which the followingis a description, reference being bad to the accompanying drawings,which are a part of this specification.

My invention relates to certain new and use ful improvements in metallicfireproof windows, and more particularly to that type of window in whicha swinging sash is employed. The object of this invention is to producea tubular sheet-metal frame thoroughly braced throughout and capable ofmaking practical weather'tight connections, with its swinging sash.

A further object of this invention is to employ an improved form ofpivotal connection for a swinging window, permitting the window to bereadily adjusted with relation to its pivotal bearing and enabling it tobe quickly and easily removed from its mounting.

With the above and other objects in view the invention consists of thedevices and parts or their equivalents, as hereinafter set forth.

Referring to the accompanying drawings, in which like characters ofreference indicate the same parts in the several views, Figure 1 is avertical section of a window embodying my invention. Fig. 2 is ahorizontal section of one side thereof, taken on the line 2 2 of Fig. 1above the pivot. Fig. '3 is a similar view on the line 3 3 of Fig. 1,taken through the pivotal connection. Fig. 4 is a vertical sectionthrough one of the pivotal bearings. Fig. 5 is an end elevation of thepivot-pin,

' and Fig. 6 is a horizontal section of one side of the window on theline 6 6 of Fig. 1.

In the drawings the window-frame is shown as comprising vertical sidecasings 8, the top casing 9, and the sill 10, all being made of sheetmetal bent in tubular'form. The side a deep central crease, in which isseated a core-plate 15, extending across the tubularstructure andriveted to the shell at the sashbearing 11. The core-plate 1.5 is alsoriveted in the crease of the back plate 14:, and thus ties the shell andback plate together, besides bracing and strengthening the tubularstructure. The crease of the back plate stands out therefrom as a flangeto firmly anchor the frame in the surrounding brickwork or masonry.

The top casing 9 is formed of. a single piece of sheet metal bent toform a tubular body riveted together, with the shoulder 13' and asash-stop 16, having the inclined bearing-surface and the dependingouter bent flange 17,

in the crease of which is seated a core-plate 18, which extends acrossthe tubular top easing and is riveted to the top thereof.

The sill 10 is bent up from a single piece of sheet metal, with inclinedtop and bottom surfaces and an upwardly extending glass seat 19, with aninner bent-over flange 20, holding in its crease a core-plate 21, whichis riveted to the bottom of the sill.

A cross-rail 22 extends across the frame from one side casing to theother and is tubular, being bent to form the glass-seat 23, with theshoulder 2a on the inner side thereof, and the inclined upper sash-stopsurface with the upwardly-projecting inner flange 25.

A flanged U-shaped strip of metal 26 is mounted on the sash-bearings 11between the sill 10 and the cross-rail 22 and is bent at its middleportion to form a pair of parallel glassholding flanges 27 and has itsside edges bent around and bolted or riveted to the shoulders 12 and 13,respectively.

A window-light 28, preferably of wire-glass, is mounted on theglass-seats 19 and 23 against flange 20 and shoulder 24 and betweenflanges 27 and is held in place by cleats 29, which are strips of sheetmetal bent double at the middle portion, with their side edges bent awayfrom each other to form a T shape in crosssection, the one edge beingplaced between the edge of the glass and the glass-seat and the otheredge bent slightly out of alinement with the first named edge to beartightly against the glass-seat.

A swinging window-sash is fitted in the upper part of the window-casingand comprises a tubular frame having side stiles formed of U-shapedshells 30, with glass-grooves 31 at their bends and their edges turnedinwardly and folded back upon themselves to form slipoints, with theoutwardly-turned edges of a bearing-plate 32 and top and bottom railsbent to form glass-seats 33, with shoulders 34 on one side thereof. Theouter bearing-surfaces of the top and bottom rails are inclined to fitthe inclined sash-stops 16 and 22, respectively, and the top rail isprovided with a weatherflange 35 at its inner edge to fit against theshoulder 13, while the bottom rail is provided with a weather-flange 35at its outer edge to fit against the outer side of the cross-rail 22.Window-lights 28 are also seated in the glassseats 33 and grooves 31 bymeans of cleats 29 1D the usual manner by employing a mullion 36 ofordinary construction.

The swinging sash is mounted on pivots in the following manner: Anangular bracketplate 37, having in its bracket or outstanding member avertical slot 38, is secured at its other member to the inner faceofeach of the side stiles of the sash by screws 39 threading nto a backplate 40, which is fastened within the stiles by bolts 41. Likewise asocketplate 42 is secured to the face of each side caslng'by screws 43threading into a back plate 44, which is fastened within said casing bybolts 45, and at its middle portion the socketplate is enlarged, forminga boss which is drilled to produce a socket 46. A pivot-pin 47 has atits medial portion a pair of oppositely-projecting arms 48, which mayeasily pass through the slot 38 to enable the rounded end of thepivot-pin being seated in the socket 46; but when the pivot-pin isturned a quarter-turn the arms bear against the side of the angularplate 37, so that a nut 49 when turned on the threaded inner end of thepivotpin rigidly clamps said pin to the bracket member of plate 37. Itis possible with this construction to adjust the sash in its frame untilthe desired fit is secured at all parts and then clamp the pivot-pins tomaintain that relation.

The slip-joints between the shells 30 and the bearing-plates 32'of thesash-stiles form projecting outer flanges 50 and inner flanges 51 oneach side of the sash, said flanges being split at the pivot parts.Above the pivots the outer flange 50 is bent back against thebearing-plate 32 and the inner flange 51 bears against the shoulder 13,while below the pivots the outer flange 5O bears against the shoulder 12and the inner flange 51 is bent back against the bearing-plate 32, sothat when the sash is in its closed position these flanges produce, withthe shoulders 12 and 13, weathertight joints the full length of thesash, and the arrangement is such that the swinging of the sash is notinterfered with. At the ends of the sash the inclined sash-bearings andthe flanges 17, 25,'and 35 complete the weathertight connections.Whenever further adjustment of the sash becomes necessary, it may bereadily accomplished by loosening the nuts 49 and adjusting the sash tothe desired position and then clamping the nuts again in their newpositions on the slotted angle-plates 37. WVhen the sash is desired tobe removed, the pivotpins 47 are turned while the nuts 49 are loose, sothat the arms 48 may be drawn through the slots 38, when thesash is freeto be withdrawn.

From the foregoing it is apparent that a window made in accordance withmy invention will be thoroughly fireproof and when the upper sash isclosed the entire structure is perfectly weather-tight.
